CHAPTER III - WATER DEMANDS

Potential water demands from the Yellow Jacket Project were identified
through questionnaires and a series of interviews with representatives from
the three functional areas - agricultural, municipal, and industrial. The
demands identified are tentative in nature. The general locations and
amounts of these demands are shown on Figure III-I.

Agricultural demands are associated with the irrigation of lands
the White River Basin within the YJWCD. About 8000 acres of

The lands were classified for irrigability in previous studies by the USBR.
All lands were placed in classes 2 and 3, with climate being the limiting
factor preventing any lands from being classified as class 1. The slopes
are about five percent on the fans and terraces while the slope of the
valley floor ranges from one to two percent. The soils are mostly alluvial
with good structure, good water-holding capacity, and low alkali and salt
content. Some localized areas may develop drainage problems if water is
applied.

The annual irrigation requirements were based on USBR estimates of
consumptive use and distribution losses. It was assumed that a pressure
pipe system would be used to provide sprinkler irrigation for the 8000
acres, which would result in an annual water requirement of about 18,000
acre-feet. The distribution of those demands by month is shown in Table
III-I.
